Circle A Sectional Office Partitions 
PREFACE 


The object of this catalogue is to give you information, data and 
illustrations of Circle A Sectional Office Partitions. They are the 
result of years of manufacturing experience, coupled with continuous 
study by a competent group of architects who have kept in mind 
the requirements of all classes of users. ‘ 


The office partition seeking to meet a universal need must satisfy 
the demands of a wide variety of individuals. 


‘The Architect and Building Owner demand satisfactory appearance, 
reasonable cost, and long life. 


The Contractor looks for low cost of material and rapid, easy erection. 


The Business Man who occupies the office insists on a dignified, 
business-like appearance and an arrangement of the partitions in 
his particular office that will give him the most efficient operation. 


4 


Circle A Sectional Office Partitions are-made in two designs. 


The Cabinet Design is carried out in a perfection of architectural 
design and detail that will add to the appearance and dignity of the 
most impressive office. The workmanship and materials throughout 
are in keeping with the very finest cabinet work. 


The Commercial Design is a simplification of the Cabinet Design. 
It is a very suitable partition for the ordinary business office. The 
proportions and general appearance are unusually attractive, but 
the details have been modified to permit of more economical manu- | 
facture. 


Both the designs are based on exactly the same principles of con- 
struction and assembly, which permit this substantial partition to 
be erected in place, or to be dismantled and rearranged, or moved 
from one room to another, practically as easily as the customary 
sectional bookcase or filing cabinets. 


This feature makes this attractive partition a PERMANENT IN- 
VESTMENT for the building owner or tenant, for it can be moved 
about any number of times to suit any desired rearrangement with- 
out damage or loss to the material.

Three Heights 


Both the Cabinet and the Commercial Circle A Sectional Partitions are furnished in the following 
heights: 
Seven-Foot, Ceiling Height, and Railing 


Seven Foot Partition— 


The seven-foot partition is the basic unit and can at any time be converted into ceiling 
height by adding the standard top assembly. 


It is shipped in seven unit parts, which can be very easily and quickly assembled to form 
a beautiful and serviceable partition. 


Ceiling Height Partition— 


The ceiling height partition is an upper partition extending from the seven-foot partition 
to the ceiling. 


It also is shipped in seven unit parts which are carefully machined so that they will fit 
together readily and accurately. 


Where the ceilings are beamed, a special construction is furnished. In this case, the 
standard ceiling height partition extends up to the bottom of the beams, and a special 
section fills up the spaces between the beams. 


Railing— 


Circle A Sectional Railing can be carried on, or out, from the seven-foot partition. 


It also is made up of seven unit parts which are so tongued and grooved that a few screws 
at the bottom and top of each section make a rigid structure with all the appearance 
and flexible advantages of the Circle A Partition.

Cabinet and Commercial Designs 


Circle A Sectional Office Partitions are made in two basic designs. Both are ex- 
actly alike in principles of construction and erection. The differences between 
them affect only their appearance. 


The Cabinet Design, shown by the preceding drawings and photographs, is pro- 
duced with the most careful attention to architectural design and detail, to meet 
the demand for an artistic, high-grade sectional office partition, which will add to 
the appearance and dignity of the most impressive business office. The workman- 
ship and materials throughout are in keeping with the very finest cabinet work. 


The Commercial Design, shown on the opposite page, is a simplification of the 
Cabinet Design. It is a very suitable partition for the ordinary business office. 
The proportions and general appearance are unusually pleasing, but the details 
have been modified to permit of more economical manufacture. 


Its plainness makes it especially suitable for factory offices or any office where the 
beauty and richness of the Cabinet Design are not of primary importance. 


The Cabinet and Commercial Designs, and the variety of woods and finishes in 
which they are furnished, offer the purchaser a wide selection both of appearance 
and of price. 


In every case they offer an exceptional quality at an unusually moderate cost. 
In addition, their erection cost is so low, as compared with that of any other type 
of partition, that the total cost of Circle A Partitions, completely installed; is in- 
variably less than any that can be compared with them in appearance, finish, or 
in strength. In no case, we believe, even in that of far more expensive partitions, 
can the purchaser get a similar solidity and flexibility.

Circle A Sectional Office Partitions 


IN THE BUSINESS OFFICE 


Partitions and railings are too commonly regarded as being primarily a luxury—insuring desirable 
privacy for occupants of offices and improving the appearance of one’s place of business. 


The competent office manager, however, regards partitions and railings as being primarily safety 
and efficiency equipment. 


They are in precisely the same class as adding machines, adequate filing cabinets, locks and safes. 
Where they are used to enclose space from floor to ceiling they are efficiency equipment, because 
the privacy and relative freedom from noise and interruption that they provide are a necessity 
for certain classes of individuals. 


Where they are used to enclose accountants and their current books and papers, office supplies, 
filing cabinets, shipping rooms, addressing departments, and the like, they are primarily safety 
equipment—protecting records from the eyes of those who should not see them, protecting mate- 
rials and files from non-routine uses, and the like. 


Where railing is used to direct traffic in the office, its primary value is to prevent waste motion, 
loitering, and undesirable interruptions of various sorts. 


In these and many other ways, partitions and railings are not merely building material; they 
are ofice equipment and should be bought and sold as such. 


What Type of Partition 
Is the Most Efficient Equipment 


Few office managers today would look with favor on the built-in files of a generation ago. 


Filing receptacles have to be moved, rearranged, and supplemented too frequently to make 
immovable equipment at all practical. 


Built-in partitions are basically just as inefficient and undesirable. 
Office layout has to be rearranged and supplemented from time to time. 


For economical and convenient rearrangement and extension, the sectional and interchangeable 
type of partition and railing is just as essential as are sectional and interchangeable filing cabinets. 
To some degree this is already recognized in practice. 


In theory it is accepted practically everywhere.

Removing the Grip of the “Dead Hand” 
ON MODERN OFFICE MANAGEMENT 


In practically every office of some size, Today’s management is both helped and hindered by 
that of Yesterday’s. 


Old methods, equipment, and layout, the work of ‘‘Dead Hands’’—work of Yesterday that was 
good at the time but which Today’s developments have outstripped—remain to hamper the 
present management. 


The old methods probably cause the least trouble. Generally they can be changed in a relatively 
short time—unless they require expensive equipment. 


Old machines are generally more troublesome. Quite frequently they are far too good to throw 
away, although there are newly-developed devices that do more and better work. As a rule, 
however, at least some of the modern equipment of this sort can be added to supplement the old. 
Most often, the grip of the ‘Dead Hands” as exerted in office layout is the hardest to shake off. 
The arrangement of private offices, open spaces, enclosed departments, and the like affects— 
vitally—practically every routine operation. 


When a factory is troubled with the same difficulty, the result is so apparent on the cost sheets 
that required changes are soon made. 


In offices, however, the cost of tearing out old partitions and building new ones always seems 
formidable. 


So the “Dead Hands” keep their grip, costs remain high, and basic improvements in operation 
remain quite impossible. 


To do away with this condition, new methods of partitioning are required. 


Circle A Partition Furniture provides these new methods. 


Keeping Office Layout Up to Requirements 


at Minimum Cost 


If partitions and railing could be moved as conditions demand, just as desks and filing cabinets 
are moved, the problem of efficient layout could be easily solved at all times. 


Circle A Partitions, because of their interchangeable unit construction, can be so moved. 


They are in effect as flexible and adaptable as sectional bookcases. Naturally, more time is 
required to set them up and take them down, but they are designed on the same principle of 
complete and extensible units. 


They are just as useful and economical for supplementary equipment as they are when used for 
primary equipment. 


With them you can provide: additional private offices, additional department enclosures, addi- 
tional traffic runways, additional railed open spaces, additional wardrobes, closets and booths.

A More Elaborate Floor Plan of an Office 
Showing Application of 
Circle A Sectional Office Partitions 


The standard units of Circle A Sectional Office Partitions can be used effectively to subdivide 
whole floors of a building, as well as a small office space. The complete partition can be erected 
without the delay, confusion and litter associated with the built-in partitions of plaster or wood. 
Valuable time in the office can be saved by installing or rearranging partitions over night. 


Erection 


Erecting Seven Foot Partition 


The erection of Circle A Seven Foot Partitions is achieved in three simple and 
standardized steps. 


First Step 


The first step consists of 
securely fastening the floor 
and wall plates to the floor _ | 
and wall. 


After the partitions are 
completely installed 
neither of these plates will 
show as they do in the 
photograph. 


The wall plate will appear 
as a pilaster of the parti- 
tion. 


The floor plates are covered and concealed by the carpet moulding. 


Second Step 


The second step consists of setting the first 
section into the groove provided in the 
wall plate. 


A standard post, grooved on four sides, is 
then set against the first section. 


The second section is then set against the 
opposite groove, another post is added, 
and the operation continued for the entire 
length of the partition.

Erection 


Erecting Ceiling Height Partition 


This operation is achieved in two simple steps. 


First Step 


The ceiling plate is fastened to the ceiling with or without the use of screws. 


Where the ceiling is beamed, there will be a space between the beams, which is filled by special 
panels. 


Sectional uprights, cut to fit without the use of screws, are inserted between the cornice and the 
ceiling plate. 


Because the top mullions are of special design, without glass stops, the transom glass is inserted 
after the uprights are in place. In taking down the partition for erection elsewhere this feature 


is especially important. 


In all other partitions the mullions have to be replaced by new ones whenever conditions in height 
change. 


Second Step 
The second step consists only of applying the crown moulding. 


The partition is then complete as shown in the accompanying illustration.

This is made possible by adjustable parts along floor and wall lines. 


A fine cabinet finish without any exposed screws or metal parts. 


Long Life 


Built sectionally, with standard parts, they are easily rearranged or removed to suit any changes 
in the organization or building. 


The small number of parts causes less loss from fitting and handling in the field. 
No exposed screws or metal to shorten usefulness by marring exterior. 

No connecting hardware to get lost or mislaid. 

Partition is built of wood members only. 


Care is used to give a beautiful durable finish. 


Strength 


Heavy construction of posts and sections with tongue and groove connection between all members. 
Does not depend on screws for strength and therefore hasa substantial, rigid construction equal 
to any specially built-in partition. 


Solid connection to floor with a concealed floor plate, and to wall with a grooved wall plate. 
Insures firm mounting. 


Heavy construction of cornice insures a substantial, rigid wall. 


Speed of Erection 


Small number of parts, held together with just a few screws, together with simple, easy mounting 
of floor plates and wall plates, allows a very rapid erection. 


Ease of Erection 


Can be rapidly and easily erected by one man. Any ordinary mechanic can follow the instruc- 
tions furnished with each shipment.

Circle A Sectional Office Partitions 
CABINET DESIGN 


Drawings 1783-1, 1796, and 1798 show the typical as- 
semblies of the Standard Units of the Cabinet Design 
Partition. 


Construction and Erection 


The posts and sections of Circle A Sectional Office 
Partitions are tongued and grooved and are held solidly 
together by anchored floor plates and a continuous cornice. 
Three screws at the bottom and three at the top for each 
section are all that are required to make a firm structure: 
Holes for the screws are provided in each section before 
shipment from the factory. 


In this way the partition is made a solid and rigid struc- 
ture from wall to wall. 


It takes only a few minutes to fit the sections and posts 
together and to fasten them by tightening the screws in 
the holes provided at the mill. 


Each piece shipped from the mill is numbered in accord- 
ance with the numbers shown on the detail drawings and 
in the erection instructions. By following these instruc- 
tions, accompanying each shipment, any ordinary me- 
chanic can erect Circle A Sectional Office Partitions easily 
and rapidly. 

Alterations can be made over-night, if necessary. 


No screw heads are exposed when the partition is com- 
plete. Its exterior is as free from metal as any other piece 


of fine cabinet work. 


Design 


Sections are built in standard widths, giving center to 
center distances between posts as follows: 

BUEN OVS Ono ner 2ee? cal Oee lien Oeme cyan) com lea OA enone 

The scribing pieces at the walls provide for a variation 
in the distance from the wall to the first post of from 414” 
to 101%”. 

Posts are grooved for connection to a continuous parti- 
tion or to a cross partition. Cross partitions and railings, 
running at right angles to the main partition, can be added 
at any post in the main partition. All that is necessary is 
to set the first section of the cross partition against the side 
of the post which is grooved to fit, starting from the desired 
post in the same manner as from the wall plate, as described 
in the preceding pages. 

Special attention to the design permits an easy adjust- 
ment to take care of any unevenness in the floors or walls. 
The joints at the floors and walls are as neat and close as 
could be secured by special built-in construction. Adjust- 
able carpet mould and plinth blocks can be removed for 
the laying of carpet or linoleum and replaced to cover the 
edges of such floor covering. 


A wiring channel built into each post and provided for 
in the design of the cornice, does away with the unsightly 
display of wires on the exterior of partitions and ceiling. 

Partitions are built to fit any height of room, and design, 


also, meets varying width conditions. Where the standard 
sections do not fill out the required length exactly, the 


24 


difference is taken up by standard scribing pieces or filler 
boards—making the partitions flexible horizontally as 
well as vertically. 


Quite as important as the vertical and_ horizontal 
flexibility is the “‘take-apart’’ feature made possible by the 
grooved construction of the standard posts and cornice. 


Hinged transom sash over the doors can be furnished 
without changing the members of the partitions. 


Small windows, such as pay windows and the like, can 
be built into regular sections at the mill at small additional 
cost. 


Marble base and plinth blocks can be substituted for 
the standard carpet mould and plinth blocks. 


Materials, Workmanship and Finish 


Only thoroughly seasoned, kiln-dried lumber is used. 
All finished lumber exposed to view is first grade. 


Structural members such as floor, wall, and ceiling 
plates, etc., hidden from view, are yellow pine. 


The doors are 13%” veneered doors, built-up core, with 
no veneering less than 4” thick, modern mortise lock con- 


struction. The panels are 3-ply veneer, cross banded. 


The standard sections are of similar construction and 


materials, but with rails and stiles cut from solid stock. 
The panels of the sections are 3-ply veneer, cross banded. 


Skilled me- 


chanics are employed and all work is executed in accord- 


Workmanship is first-class cabinet type. 


ance with the best shop practice for cabinet work. 


All exposed surfaces are carefully hand scraped and sand- 
ed, to remove mill-marks and other imperfections, and to 
avoid rounding corners and edges. In this way the char- 


acter and sharpness of profiles is preserved. 


The sections as assembled at the mill and all members 
of fixed lengths are mitre jointed, except where butt joints 
are necessary, in which case the ends are carefully squared 
to insure hair joints. 


The partition carried in stock is in our oak and birch. 
Other hardwood such as gum, walnut, mahogany, and 
the like are furnished to order only. 


Unless otherwise specified, partitions will be filled, stain- 
ed, and shellaced at the mill, in accordance with sample 
of finish, furnished or approved by the customer. When 
specially noted, partitions can be shipped in the white, or 
finished with an extra coat of varnish, or with a rubbed 


finish. 


Shipping 

Partitions are shipped crated, knocked down, without 
glass, including all hardware for doors, ready for erection. 
Large shipments making a carload are not crated. 


Hardware 


Unless otherwise specified all doors, and transoms are 


fitted with dull black, ‘“‘Bower Barff’’, finished hardware.

Circle A Sectional Office Partitions 
COMMERCIAL DESIGN 


Drawings 1823, 1799, and 1795 show the typical 
assemblies of the standard units of the Commercial 
Design Partition. 


Construction and Erection 


The posts and sections of Circle A Sectional Office 
Partitions are tongued and grooved and are held 
solidly together by anchored floor plates and a con- 
tinuous cornice. Three screws at the bottom and 
three at the top for each section are all that are 
required to make a firm structure. Holes for the 
screws are provided in each section before shipment 
from the mill. 

It takes only a few minutes to fit the sections and 
posts together and to fasten them by tightening 
the screws in the holes provided at the mill. In this 
way the partition is made a solid and rigid structure 
from wall to wall. 

Each piece shipped from the mill is numbered in 
accordance with the numbers shown on the detail 
drawings and in the erection instructions. By fol- 
lowing these instructions, which accompany each 
shipment, any ordinary mechanic can erect Circle 
A Sectional Office Partitions easily and rapidly. 


Alterations can be made over-night, if necessary. 


No screw heads are exposed when the partition 
is complete. Its exterior is as free from metal as 
any piece of fine cabinet work. 


Design 


Sections are built standard widths, giving center 
to center distances between the posts as follows: 


4’—4", 3’—10", 3’—_4", 2’—10”, 2’/—-4", and 1’—10”. 


The scribing pieces at the walls provide for a 


variation in the distance from the wall to the first 
post of from 414” to 1014”. 

Posts are grooved for connection to a continuous 
partition or to a cross partition. Cross partitions 
and railings, running at right angles to the main 
partition, can be added at any position in the main 
partition. All that is necessary is to set the first 
section of the cross partition against the side of the 
pest which is grooved to fit, starting from the de- 
sired post in the same manner as from a wall plate 
as described in the preceding pages. 


Special attention to the design permits an easy 
adjustment to take care of any unevenness in the 
floors or walls. The joints at the floors and walls 
are as neat and close as could be secured by special 
built-in construction. Adjustable carpet mould 
and plinth blocks can be removed for the laying 
of carpet or linoleum and replaced to cover the edges 
of such floor covering.

Partitions are built to fit any height of room and 


design, also, meets varying width conditions. Where | 


the standard sections do not fill out the required 
length exactly, the difference is taken up by stand- 
ard scribing pieces or filler boards—making the

Quite as important as the vertical and horizontal 
flexibility is the ‘“‘take-apart’’ feature made possible
